When COVID-19 started, Noom users ate less fruit and vegetables, but more red meat and starchy vegetables, compared to before COVID-19 began.
The most successful Noom users (in terms of weight loss and engagement) had the highest mental health quality of life, work-life balance, and flourishing (a sense of meaning and purpose in life). The higher users’ anxiety, the less weight they lost.

Noom users with greater weight loss reported consuming healthier foods (higher fruit and vegetable intake, better dietary quality) made healthier food choices at 18 months. Noom users with greater weight loss also adhered more to the food color system.
A novel technique (computerized linguistic analysis) was used to understand Noom users’ emotional journey over time. Noom users used more negative emotion words over time, which was marginally associated with better weight loss. Users with more specific YBPs wrote with more positive emotion than users with more abstract YBPs.

40 patients with type 2 diabetes were randomly assigned to use Noom or to a control group. Significantly more patients in the Noom group achieved target A1C levels compared to the control group.
In this randomized controlled trial, participants at high risk for (but undiagnosed) metabolic disorders lost significantly more weight and body fat mass with Noom (including coaching) than Noom without coaching or a control group.
Time series analysis was used to look at relationships between logging and weight loss. Logging was associated with weight loss for women but not for men.
In this study, participants were given a monetary reward if they logged their food three times a day. Those who logged three times a day during Noom lost significantly more weight and read more articles and exercised more compared to those who did not log three times a day.
This randomized controlled trial showed that Noom’s Diabetes Prevention Program (DPP) resulted in significant weight and BMI reduction at 6 months and 12 months.
Noom’s Healthy Weight and Diabetes Prevention Program both resulted in significant weight loss. Healthy Weight users lost 6.24 kg (5.2% body weight) and DPP users lost 5.66 kg (8.1% body weight) by week 52.
Noom plus cognitive behavioral therapy reduced binge eating days and improved remission in adults with binge eating compared to standard care.
Noom with digital cognitive behavioral therapy resulted in significant weight, fat, leptin and insulin resistance, emotional eating, snack calorie intake improvements compared to a control group.
In conjunction with local healthcare treatment, Noom reduced body weight by 2.73 kg, decreased fat mass by 2.65 kg, and significantly increased metabolic equivalent of task (MET) after 8 weeks.
A qualitative study found that coaches trigger reflections on users’ habits, jointly help users determine measurable health goals, facilitate self-evaluations on recent behavior change, and tailor programs to adapt to users’ lifestyle and health status.
In this randomized controlled trial, Noom users with colorectal polyps (a precancerous growths in the colon) lost significantly more weight than individuals who did not use Noom. Engaging with the Noom app significantly increased exercise.
Compared to a control condition, only Noom reduced empty calorie consumption, and total kcal and total fat intake showed larger reductions for Noom in pre-bariatric surgery patients.
Significant weight loss in pre-diabetic Noom users was sustained to 65 weeks, weight loss ranged from 6.15% to 8.98% of body weight.
Air pollution significantly negatively predicted weight loss (the more air pollution, the less weight lost) for a subset of Noom users around the world.
Perceived support from groups significantly promoted Noom users’ engagement and weight loss.
A Noom hypertension program significantly improved weight by 3.05 kg, diastolic blood pressure by 5.06 mm Hg, and hypertension category at 24 weeks.
Metabolic risk factors were improved by 15 weeks, and significant weight loss was sustained at one year.
Self-efficacy was positively associated with food logging, which was positively associated with weight loss success. Social support received from the Noom group was related to an increase in food logging and group participation, and group participation was positively associated with weight loss.
BMI was reduced in Noom users by 2.59 kg/m2. Higher adherence led to higher weight loss.
There was a direct and independent impact of meteorological conditions on intentional weight loss efforts on a global scale.
Noom paired with cognitive behavioral therapy for binge eating significantly reduced bulimic episodes, greater meal and snack adherence, and regular meal adherence compared to traditional guided self-help.

Pre-diabetic Noom users lost significant amounts of weight at 16 weeks (5.65-6.33%) and 24 weeks (6.58-7.50%).
77.9% of over 35,000 participants lost weight while using Noom.
